A coin is flipped twice. What is p(H then T)?
The probability of getting heads (H) on the first flip is 1/2. If H is obtained on the first flip, then the probability of getting tails (T) on the second flip is also 1/2. Therefore, the probability of getting H then T is:
P(H then T) = P(H) x P(T | H)
P(H then T) = 1/2 x 1/2
P(H then T) = 1/4 or 0.25
Therefore, the probability of getting H then T is 1/4 or 0.25.
To find the probability of getting a Heads (H) followed by a Tails (T) when flipping a coin twice, we can break down the process into steps:
Step 1: Determine the probability of getting a Heads (H) on the first flip. Since a coin has two possible outcomes (H or T) and they are equally likely, the probability of getting H on the first flip is 1/2.
Step 2: Determine the probability of getting a Tails (T) on the second flip. Again, since a coin has two possible outcomes (H or T) and they are equally likely, the probability of getting T on the second flip is 1/2.
Step 3: Multiply the probabilities from Steps 1 and 2 together to find the probability of getting H then T: (1/2) * (1/2) = 1/4.
Therefore, the probability of getting a Heads (H) followed by a Tails (T) when flipping a coin twice is 1/4 or 0.25.
To calculate the probability of getting a sequence of outcomes, you need to consider the probability of each individual outcome and then multiply them together.
In this case, the probability of getting a heads (H) on the first flip is 1/2, since there are two equally likely outcomes (heads or tails) and only one of them is heads. Similarly, the probability of getting a tails (T) on the second flip is also 1/2.
To find the probability of both events happening together (H then T), you multiply the individual probabilities:
P(H then T) = P(H) * P(T) = (1/2) * (1/2) = 1/4
So the probability of getting a heads on the first flip and tails on the second flip is 1/4.
